Standard screws

The screws 'naturally ' become loose due to various constraints.



These constraints being :


A heavy axial load which leads to the falling of the materials, which then reduces the tension of the screw.

The vibrations and shocks provoke very small movements which then causes the rotation of the screws to unscrew.

The change in temperatures incites differential expansion which can erase the tension in the assembling.

For all these reasons, it is advised to secure all threaded assemblies by thread locking.



THE LOCKING OF THE SCREWS CAN BE ASSURED IN 2 WAYS:


 By the bonding of threaded elements due to a micro-encapsulated adhesive which activates during the screwing.

 By increasing the rubbing during the assembling, generated by a polyamide elastic cord, which has been placed on the threads. The polyamide locking is less performant than bonding but enables to reposition the screw several times.

The sealing performance can also be integrated to the screwing by pre-coating. The screws are then pre-coated by a sealing resin to replace a flat or toric joint under the screw head, or to eliminate the sweating of the female thread.

The seizing of the screw can also be a solution for pre-coating. The thread is then pre- coated with an anti-gripping, which favors the mounting and the dismantling of the assembling, particularly where there is excess loads and high temperatures.

Soprima provides to his customers the SOPRIFIX range. No need to supply standard screws and a locking product : SOPRIFIX is the right solution.

Screws and nuts already pre-coated.
